Abstract:
A method and an apparatus are provided for decoding a channel in a communication system using a LDPC code. A shortening pattern and a puncturing pattern are determined based on a received signal. A value of a shortened bit is set to 0 according to the determined shortening pattern, erasures are set according to the determined puncturing pattern, and LDPC decoding is performed, when bits exist which have been used to perform shortening or puncturing. Determining the shortening pattern and the puncturing pattern includes setting a predetermined ratio of the number of punctured bits to the number of shortened bits.
